Living in a building of architectural significance, one is not so much a homeowner as a custodian – but there are few so well-suited to the role as Annette. The CEO of Museums of History NSW, Annette’s work is driven by a passion for the past. This has overflowed into her personal life, as she and her husband Michael are the owners and meticulous caretakers of the Walter Burley Griffin-designed Duncan House in Castlecrag.

Annette and Michael’s love of heritage homes is longstanding, and when the couple moved from Melbourne to Sydney and began house hunting, a period gem was high on their list of must-haves. “We were looking for something that hadn’t realised its full potential, that had architectural significance and heritage value to it. I love a project,” says Annette.

Who lives here?

Annette, CEO of Museums of History NSW; Michael, a finance industry executive; and their two cats, Lexi and Boo.
What do you love most about historical homes? Annette: “Their character and warmth. They display craftsmanship that we could only dream of achieving today and their patina tells stories of the families who lived there before.”
What is the biggest challenge of living in a heritage home? “As a custodian of a heritage home, you have a responsibility to future generations to respectfully conserve its heritage fabric. That’s a lot of pressure!”
And the biggest reward? “Living in a true one-of-a-kind space. I get enormous delight from the quirks of the house – the curved skirting boards, the chevron-shaped windows and the shiny ochre ceilings.”
What is your favourite space in or around the home? “The gardens are very important to the house and I love that visitors pass through the garden to enter our home. There are so many lush outdoor spaces to enjoy from all areas of the house.”

Jan Spencer, a former owner of Duncan House, worked in interior design and was influenced by Marion Hall Best, Sydney’ ‘it’ designer of the mid-20th century, whose signature was coloured stipple-glaze ceilings. “Jan, in a nod to her work, and in frankly a stroke of genius for the house, chose that finish and it suits the house so incredibly well,” says Annette of the existing ceilings. She continued the earthy scheme with a Globe West sofa, ‘Alva’ lounge
chairs by Ellison Studios and art by Kawayi Nampitjinpa, Kim Napurrula and Rosie Nampitjinpa from Papunya Tula Artists. (Credit: Photography: Alana Landsberry, Styling: Lucy Gough)

The suburb of Castlecrag piqued the couple’s interest – surrounded on three sides by Sydney Harbour, the land was originally developed in the 1920s by Walter Burley Griffin and his wife Marion Mahony Griffin, architects who formed a groundbreaking vision of a community built in sympathy with the natural bush landscape. Duncan House is one of 13 Griffin homes in this unique area.

“There aren’t really any square corners in the old part of the house – it’s a subtle nuance.” Annette

Although redundant – the new extension features the main kitchen – the original kitchen had to be preserved in line with heritage conservations restrictions. Behind the half door, which folds into a ledge when closed, it stands as a fascinating snapshot of life in the 1930s. (Credit: Photography: Alana Landsberry, Styling: Lucy Gough)

It had been largely preserved, but also bore the scars of questionable design decisions made in recent decades. “The house was in a state of promise. But not a lot of realisation of that promise,” explains Annette.

The old tapware in the original kitchen was replaced with a new Brodware set in a sympathetic style, but the zinc benchtop is original, as are the cabinets, which were stripped back and colour-matched to the green chosen by the home’s first owners, Anice and Frank Duncan.

There were two parts to the project: conservation work on the original dwelling, and a larger renovation on an ill-advised ’90s extension. The first tool in the couple’s renovation kit was knowledge. “I spent about six months researching online and found great information through council, the Griffin Society and the Caroline Simpson Library. I learnt so much about the house and came to understand what had been changed over the years,” says Annette.

At the junction of old and new, the kitchen celebrates the original sandstone. “I wanted that sandstone wall to be the hero,” says Annette, who teamed it with a scheme of Taj Mahal quartzite benchtops and Fibonacci terrazzo floor tiles. “It’s organic, it’s earthy, but it’s not so figured that it detracts from the sandstone.” (Credit: Photography: Alana Landsberry, Styling: Lucy Gough)

While the conservation work on the cottage, built in 1934, was no small job, the most dramatic transformation has been to the extension, which architect Robert Weir of Weir Phillips Architects was brought in to reinvent. The brief to Robert could be boiled down to two major goals.

The first was to reconnect the Griffin house with the street – Castlecrag is a must-visit stop for architecture buffs, but this one was cowering behind the ’90s addition and a hulking carport. “The second big move was making the original Griffin building the hero and the extension subservient. We aimed to get a better dialogue between the extensions and the original house,” says Annette.

An early extension at the rear, designed in the 1940s by a friend of the Griffins, houses the study (this page). Annette and Michael updated it with a series of Griffin-esque double doors, allowing light to pour in and opening up the space to its bushland setting. In furnishing the room, Annette was mindful of the Griffins’ philosophy of connecting with nature, so chose a botanical hero piece: a round House of Heras ‘The Bees Knees’ rug from Designer Rugs.

It’s an early example of that prous indoor outdoor living style that is so fashionable now.” Annette

This was a multi-layered process that involved channelling the architectural language of the Griffins and intentionally subverting it. “Burley Griffin stuff is quite muscular, there’s a real depth to the walls,” says Robert, who contrasted this with floating exterior panels and glazed corners, including the dining room corner, which looks onto the heritage home from the extension. “That corner becomes like a giant lantern, like a beacon to the front courtyard,” he says.

The home is built using Walter Burley Griffin’s patented Knitlock bricks, which feature in the guest room. “They’re cement with sand and crushed oyster shells pressed into the surface, so they’ve got this really organic lustre to them that is stunning and unusual,” says Annette.

“I get enormous delight from the quirks…the curved skirtings, chevron windows and shiny ochre ceilings.” Annette

Marion Mahoney Griffin’s ‘Forest Portrait 12’ watercolour was enlarged and translated to wallpaper by Colour Factory for the couple’s room. “I conceived that idea of the wallpaper as a way of honouring the Griffins in the new part of the house,” says Annette.

Glazing was a key component of the build, with great banks of glass revealing the Griffin home from within the extension, as well as connecting it with the garden. “We wanted the extensions to have that same permeability [as the old] and that same flow between inside and outside,” says Annette.

“My wall tiles are my favourite finish in the entire house,” says Annette, who chose round-edged Dtiles for the bathroom walls.

Interior design in a space as singular as this is no easy task, but Annette found ample inspiration in the original home and the surrounding bushland. “I aim to create balance and connection between things,” she says.

As such, colours and botanical patterns were drawn from nearby nature and subtle curves in everything from tiles to light fittings speak to the rounded corners and contoured crenellations of the original build. Annette jokes that she agonised over every detail, but there’s no doubt the result is worth it. With their eye for the extraordinary, the Griffins would surely approve.

30s Architectural Pioneers

Titans of Australian architecture, landscape design and planning, Walter Burley Griffin and his wife Marion Mahony Griffin (an architect
and artist) came to Australia from America in 1913 after winning the Federal Capital Design Competition to plan the city of Canberra. From
this ambitious work, they went on to design more than 350 buildings and urban projects, including the Sydney suburb of Castlecrag.

The Griffins’ style was influenced by their work with architect Frank Lloyd Wright and his Prairie School design ethos, which dictated that buildings should be connected yet subservient to their surrounding natural environments.

This is clearly seen in the porosity of their building design, which contrary to convention, featured living areas at the rear of homes, openings to the landscape and few – if any – fences. The unique planning of Castlecrag was groundbreaking for its time, and the iconic suburb was designed in sympathy with its pristine bushland surrounds. It follows the contours of the land and sweeping curves of theforeshore, marked by a meandering network of roads and walkways, and with buildings designed to be nestled within and minimise the impact on the unspoilt bush.

The naturalistic garden is as much of a design element as the home itself. “The original house is tiny, but it has eight sets of double doors to the outside, so the garden is meant to be an extension of the house’s living spaces,” says Annette. Landscape architect Melissa Wilson refined the heritage-protected garden, which spills onto a reserve at the rear. “There are so many lush outdoor spaces to enjoy from all areas of the house,” shares Annette (Credit: Photography: Alana Landsberry, Styling: Lucy Gough)

WE LOVE…a sense of arrival

In an architectural sleight of hand, a new landscaped path bypasses the seldom-used front door and guides guests down past the extension, encouraging them to enter at the courtyard junction between old and new. “The idea was to enter the building at the original Burley Griffin piece, so that courtyard is kind of an external lobby. There’s no real, discernible front door, but Burley Griffin didn’t have one, either! You just arrived at the building and there were a whole lot of French doors and you could walk in any one you wanted to.” explains architect Robert Weir.

Nestled in nature, this Sydney heritage-listed Walter Burley Griffin icon helped weave the fabric of contemporary Australian architecture. To bring the 1930s sandstone cottage into the 21st century, it needed a sensitive
addition and dedicated custodians, which it found in homeowners Michael and Annette. The original home’s exterior, in Resene Akaroa, is almost luminous in comparison to the dark extension in Resene Karaka. Kitchen The
cabinetry colour, Resene Raptor, was chosen to tone with the bushland setting amid a palette of natural materials. (Credit: Photography: Alana Landsberry, Styling: Lucy Gough)
